Already mixed and priced per bottle, so not compared per milligram with a vial of powder.

Coverage record →Three things the price does not tell you
A cheap sticker price only counts if the package is right.The label is a claim, not a measurement
The amount printed on the bottle is the vendor's claim, not a lab measurement. Compare offers by what each label states before judging value.
Shipping and card fees are not in these numbers
Shipping is often flat, so it hurts small orders most. Several vendors add a card fee and discount for crypto. Two offers a dollar apart can swap places at checkout.
Bigger packages look cheaper and expire just as fast
Compare liquids by their stated concentration and bottle volume. A larger package only saves money if you can use it within the product's labeled shelf life.
How wide the price gap really is
Same compound, same buyers, very different tickets.Ignoring the few freak listings at each extreme, the dear end of the Letrozole market costs 1 times what the cheap end does, per milligram.
Half these listings charge more than this per mg and half charge less. It moves with sales, which is why every row carries a date.
Enough coverage to show a real range. Anything under three vendors stays off the hub.
What you are actually buying
Regulatory status changes what a price means.
FDA-approved
First approved in the US in 1997, for hormone receptor-positive breast cancer in postmenopausal women. The label contraindicates it in women of premenopausal hormonal status and states that clinical benefit in premenopausal women has not been demonstrated. There is no approved use in men. It carries warnings on bone mineral density and on total cholesterol, and product monographs also note tendonitis, tenosynovitis and rare tendon rupture across this drug class. Prohibited in sport at all times by WADA under section S4.
Full Letrozole record →Nobody stands behind a research product
There is no pharmacist behind it, no dispensing record, and nobody on the hook for what is inside the bottle. The lab report is the whole quality system, which is why it sits next to the price here.
Research use only is a claim the seller has to keep making. A vendor that adds dosing instructions, health claims, or personal-use wording has stepped outside the framework it relies on, and that says something about the seller.
What customs and carriers do varies by state and by shipper. This describes how these products are sold and is not legal advice.
Before the bottle arrives
These offers describe ready-made liquid, not dry powder.
Check the bottle's storage directions
The tracked offers state a liquid concentration. Follow the specific product label's storage and use-by directions rather than a freeze-dried vial's post-mixing timeline.
No powder to reconstitute
The listings describe a solution, not a dry vial. Check the stated concentration and intended handling on the product label; powder-mixing instructions and bacteriostatic water do not apply.
Compare concentration and volume together
Compare the stated concentration, bottle volume and total price. A larger bottle is not automatically the better value if it cannot be used within its labeled shelf life.

How this table is built
What decides the order of the rows, and who gets to be in them.Cheapest per mg first, and nothing else
Rows sort on one number. There is no combined score and no weighting, so no vendor can be pushed up the table by a rating you cannot check.
Doing badly does not get a vendor removed
Vendors that publish nothing stay in the table, marked. Taking them out would make the market look tidier than we found it.
Every price has a date on it
Prices are read off public catalog pages and saved with the date. If a check runs late the row says so instead of showing an old price as current.
Sorting never reads who pays us
Commissioned links are marked on the row and listed on the disclosure page. They never move a listing up or down the table.
How these prices are collected
Prices on this site are read from vendor websites on the dates shown. A starting tag means the vendor publishes only a from price for that product. A wall means the vendor hides prices behind a login, and we publish that fact rather than hide the gap.
We report prices and never rate or score an offer. There is no value grade, no ranking of vendors by our opinion. A row carries its size, its price, its price per milligram, and any plain fact about the listing worth knowing.
When a vendor's site disappears, its rows stay in the tables as a dated record, drop out of every count, price range and ranking, and lose their links. Ninety days after a vendor's site disappears, its rows leave these tables and remain in our records.
Some vendors pay this site a commission when you buy through our links. Every one of those links is marked, and every vendor with that arrangement is labeled on the vendor page. Commissions never change the prices we show, the order of any table, a vendor's badge, or anything in the audit record. The data is collected the same way for every vendor, paid or not.
We accept no payment for coverage, placement, or ratings. Warning letters come from fda.gov. If a paying vendor earns a bad mark, the mark stays.
Questions about buying letrozole
Cost, sizes, and how this table works.How much does Letrozole cost?+
We track 3 listings across 2 vendors. No vial size has 3 or more exact in-stock prices, so there is no per milligram range. The table above shows every price we have read.
Why is the same product so much cheaper at one vendor?+
Package size, sale cycles, payment method discounts, and how much testing evidence a seller publishes all move the number. A cheap price is only cheap if the product holds what the label claims, which no price column can tell you.
Do you make money if I buy?+
Sorting never reads whether a vendor pays us. Any commissioned link is marked on the row and listed on the disclosure page, and it never changes where a listing lands in the table.
Is letrozole legal to buy?+
First approved in the US in 1997, for hormone receptor-positive breast cancer in postmenopausal women. The label contraindicates it in women of premenopausal hormonal status and states that clinical benefit in premenopausal women has not been demonstrated. There is no approved use in men. It carries warnings on bone mineral density and on total cholesterol, and product monographs also note tendonitis, tenosynovitis and rare tendon rupture across this drug class. Prohibited in sport at all times by WADA under section S4.
How current are these prices?+
Every price is read off a public catalog page and stored with its date; this compound was last read Oct 10, 2026. Nothing is overwritten, so a stale row says so rather than pretending to be current.
